Using that right now. I've died at the Iron Golem about 4 times now. His "grab and smash me into the ground" move always gets me. Tough to figure out the range on that. He seems to always scoop me.

Make sure you use the lightning spear because it'll stun him worse and worse over time. If you strafe to his sides constantly, his grabs and attacks should miss. You can also go human and summon the Iron Turk (some name like that) in the room across the small bridge near the boss room. That dude will kill the boss for you basically, he's very strong.
